For people living with both Type 2 diabetes and heart failure, taking an aspirin each day appears to lower the risk of dying or being hospitalized for heart failure, according to research being presented at the American College of Cardiology’s 67th Annual Scientific Session. But the data also reveal aspirin use may increase the risk of nonfatal heart attack or stroke, a somewhat contradictory finding that surprised researchers.
The study is the first to assess aspirin as a preventive measure for patients who have both diabetes and heart failure. Aspirin, a blood thinner, is strongly recommended for patients who have previously had a heart attack or stroke, but guidelines are unclear regarding its use as a preventive measure for patients who have cardiovascular risk factors but no history of heart attack or stroke. Previous studies in people who have not had those types of health events have shown conflicting evidence of aspirin’s potential benefits in the general population. In patients with heart failure, some studies suggest a daily aspirin may even be harmful.
About 27 million people in the U.S. have Type 2 diabetes and about 6.5 million U.S. adults have heart failure, a condition in which the heart becomes too weak to pump enough blood to meet the body’s needs. Each condition is associated with an elevated risk of cardiac events, including heart attack and stroke. This study sheds new light on the potential risks and benefits of aspirin for people with both conditions.
